Flextimer: Design Your Time

Build flexible timers with custom steps, rounds, and cues for sounds, vibration, color changes, and countdowns.

Flextimer helps you build custom timers for workouts, interval training, focus sessions, breathing exercises, presentations, routines, and more.

Design sessions with ordered steps, repeating rounds, labels, and colors. Add cues to any timer step for additional sounds, vibration, color transitions, or countdowns. Review total time, time by color, cue details, and progress behavior before you start a session. Easily fit every part of your session, from prep and work to breaks and cooldowns.
